Full technical migration of a Drupal 8/9 site to Drupal 11, ensuring zero data loss, minimal downtime, and a clean upgrade path for long-term maintainability.
The Process
Module Compatibility Audit: Reviewed every installed module for Drupal 11 compatibility. Identified deprecated modules and mapped replacements or custom alternatives.
Custom Code Refactoring: Updated all custom modules and themes to comply with Drupal 11 coding standards, including dependency injection patterns and updated API calls.
Configuration Migration: Exported, cleaned, and re-imported site configuration to ensure a smooth transition between major versions.
Content Migration: Preserved all content entities, taxonomy terms, user accounts, permissions, and media assets throughout the upgrade.
Testing & QA: Ran comprehensive cross-browser and functional testing on a staging environment before deploying to production.
The Result
A fully modernized Drupal 11 site with improved security, better performance, and access to the latest Drupal ecosystem features and long-term support.
